IPC: H04N1/04
Filed: 1927-07-27
Abstract: 300,148. Wright, G. M., and Smith, S. B. July 27, 1927. Copying-telegraphs. - In a copying-telegraph transmitter a constant ratio is maintained between the frequencies of periodic devices 19, 12 controlling respectively the alternating current superimposed on the picture currents and the speed of the drive of the scanning mechanism. When the superimposed alternating current is produced electrically, it is derived from the same source 18 that drives the scanning mechanism. A photoelectric cell 11 is subjected to light varying in accordance with the object which is scanned by optical apparatus driven by a motor 12 which is energized by a source of current 18 controlled to a constant frequency, for example by a tuning fork. The source of current is also connected to the input of a frequency changer 19, the output of which is superimposed on the electric output of the photo-electric cell. When the superimposed alternating current is produced optically, a lined screen is interposed in the path of the light so that the rate at which the light traverses the lines is proportional to the speed at which the picture is traversed by the scanning mechanism (Fig. 2, not shown). A colour filter 23 is inserted in the path of the light exploring the object to exaggerate contrast in the object. Specification 276,399 is referred to.

Title: Centralised Cyclic Lubrication System.
Inventor: GRUBER THOMAS JOSEPH
IPC: F16N25/02
Filed: 1968-04-26
Abstract: 1,186,996. Lubricating. EATON YALE & TOWNE Inc. 26 April, 1968 [16 June, 1967], No. 20009/68. Heading F2A. A centralized cyclic lubrication system having a motor 60, Fig. 1, a pump 68 and one or more positive displacement type measuring valves, comprises a timer 54 for periodically actuating the motor 60 and the pump 68 to distribute lubricant to the measuring valves, a first timer switch coupled to the timer, a clutch coupled to the timer for re-setting the timer, means to transfer the first timer switch from a passive position to an active position to thereby supply power to the motor 60 for operating the pump 68 of the lubrication system, and means responsive to the completion of the lubrication cycle in the lubrication system for activating the clutch to thus reset the timer to a starttiming position and to interrupt power to the motor 60. The timer has a second timer switch responsive to the passage of a pre-determined timed interval after the actuation of the first switch, the second timer switch terminating the operation of the timer and activating an alarm. The motor 60 and the pump 68 are mounted on a platform 58 of a casing 32 and the timer 54 is attached to the casing 32. The motor 60 is mounted on a bracket 62, and is connected to the pump 68 by a coupling 66. Lubricant is pumped from a reservoir 40 to the valve 82, via a strainer 72; pipes 70, 74; and a passage 76, formed in the bracket 62. The valve 82 is attached to the bracket 62; comprises a main body 92, Fig. 4, with end-caps 94, 96 secured thereto, the latter having a limitswitch 102 mounted thereon; and has a reversing valve 90 bolted thereto. The body 92, having a bore 118, receives a hollow two-landed spool 103 therein; and, having radial bores, receives a ball relief valve 108 and connects to the reversing valve 90. Each end cap 94 or 96 is bored to receive a piston 122, the latter being connected to the spool 103 by a member 110 or 112. The piston 122 in the end cap 96 has an extension 126 engageable with a roller 130 of the limit switch 102. The system can operate with various types of positive displacement measuring valve systems including, for example, a standard two-line system having metering valves V, Fig. 11, and a pair of lubricant lines L1, L2. A motor M drives a pump P which pumps lubricant from a reservoir to a 4-way valve. Pressurized-oil is passed through the line L1 to the metering valves V. When all the lubrication points served by the line L1 have been lubricated, line pressure builds up and actuates the flow-reversing valve (pilot). The limit switch is actuated and the pump is stopped, one half of the lubricating cycle having been effected. Actuation of the timer control repeats the above sequence to serve the line L2. The timer is the off-delay type having its clutch spring-engaged to a timing cam which operates the timer switches.

Filed: 1971-04-19
Abstract: 1329762 Automatic exchange systems SIEMENS AG 19 April 1971 [23 Jan 1970] 20185/71 Heading H4K In a multi-exchange system each exchange records a list of the subscribers served by that exchange and a wanted subscriber's identity is sent out as a search request from the exchange of the calling subscriber and is relayed from exchange to exchange throughout the system, each exchange recording a search request with a note of the channel over which it was received so that it can return a connect signal if it serves the wanted subscriber, or can forward the request if it does not, repeat receptions of a request from exchanges other than the first to present it being ignored and exchanges providing such repeat requests being cleared of the request if they have no other adjacent exchange to which the request may be usefully sent. Recording of a received request is acknowledged by a signal reverted to the exchange from which the request was received. Having cleared exchanges of a request when they have no useful outlet for further promulgation of the request, it becomes possible to clear those other exchanges whose usefulness in the search is exhausted since their function has been to relay the search request to an established dead-end. With clearing down of search request records in this manner the only records that survive are those marking a single route to the exchange that sooner or later locates the wanted subscriber. If the connect signal sent from the exchange of the wanted subscriber fails to result in a connection it may be repeated. If the connect signal received at the exchange of the calling subscriber is defective and makes it impossible to complete the connection, the exchange can initiate a new search for the wanted subscriber. The channels over which the search request is promulgated may be held in anticipation of their use in connecting the calling and called subscribers, or they may be released after the search request transactions are complete, the final connection requiring the seizure of channels along the route marked out by the search request records. The interexchange links may be wire or radio links and employ frequency or time-division multiplex with amplitude or pulse-code modulation.

Abstract: 642,533. Cathode-ray oscillographs. STANDARD TELEPHONES & CABLES, Ltd. July 6, 1946, Nos. 20238 and 20239. Convention dates, July 9, 1945, and July 14, 1945. [Class 37] [Also in Groups XL (a) and XL (c)] A plan-position indicator display in a radar system is associated with a light-filter which is mounted in front of the display and rotates in synchronism with the rotating radial trace thereof. In the embodiment described the filter is graded so that maximum attenuation of the indications occurs just after they are produced and the filter density then decreases uniformly until no attenuation occurs just before the next '' paint," so that as the indications fade they are attenuated progressively less and an appearance of a constant intensity display is produced. Moreover, indications produced during the previous aerial scan by objects which have since disappeared are rendered invisible by the high density of the filter as the radial trace passes. The Specification as open to inspection under Sect. 91 also describes filter discs, as shown for example in Fig. 10A (Cancelled), comprising a narrow radially-extending filter portion which may be used to reduce the intensity of the brilliant blue line produced by the rotating radial trace without attenuating the afterglow. A filter-disc having a narrow diametrically-extending portion is also described. This subject-matter does not appear in the Specification as accepted.
